dovecot - Dec 2006 - Enabling different quota limits for different users for /etc/passwd as userdatabase on FC3

hey friends,

 I am running my company's mail server on FC3 which comprises of
Postfix + Dovecot + MailScanner + Clamav + Squirrelmail + MailWatch +
Spamassassin. I am using Dovecot 0.99.13-3 version on FC3 and I want
to implement Quota limits for the users.

I am using userdatabase as /etc/passwd file (auth_userdb = passwd )
and password database as pam(auth_passdb = pam) for dovecot. I read
the documentation of dovecot but the quota example for /etc/passwd is
missing. I want to have different quota limits for different users
for example Quota limitation will depend upon the users, well there
will be a global quota limit which will takes place if there is no
limit specified for that particular user.

Can anybody guide me how to configure quota's for different users in
dovecot for /etc/passwd as userdatabase and pam as password database.

Please let me know if you need any further inputs.

Thanks & Regards

First of all you can't use quota with 0.99.x Dovecot. You'll need to use
a recent 1.0rc release.

It's missing, because there's no way to add extra information
for /etc/passwd without breaking other software that reads it. You'd
pretty much have to use userdb passwd-file, and create a copy of
your /etc/passwd to some passwd.imap and add the quota stuff there.

Well, except I suppose you could also change mail_executable to a script
which sets QUOTA-environment (you can figure out where it gets the
user's quota) before executing imap.
